This item has been discontinued and replaced by the Raspberry Pi Model B+ Embedded Linux Microcontroller.
The Raspberry Pi Model A is a low cost ARM controller capable of running the Linux operating system. It was developed by the Raspberry Pi Foundation in the UK for the original purpose of teaching kids about computer science and programming. Advanced roboticists can use the Raspberry Pi as a very capable embedded Linux robot controller.
This board provides a powerful microcontroller featuring a Broadcom BCM2835 "system on a chip" design which includes an ARM1176JZF-S processor running at 700Mhz with 256MB of RAM. The tiny board also includes an SD card reader and one USB port as well as audio and video outputs. A set of 8 GPIOs, a UART, I2C and SPI are available for use with robotic projects. It boots from an SD card that generally contains a Raspberry Pi compatible Linux operating system and user programs.
The Model A board differs from the Raspberry Pi Model B in that it has less memory, no Ethernet port and only one USB port. This board may be better suited for robotics applications because it uses less power.
